Candidate: Open Supervisors: Kerry Leith, Matthew Perras Institution: ETH Zurich, York University Activity: Beginning Fall 2018 Exceptionally warm summer temperatures in northern Europe during the summer of 2014 were accompanied by active fracturing and small rockbursts from flat-lying postglacial bedrock surfaces on a small Finnish Island. Employing a new portable acoustic emission detection system, this project will investigate […]

Matthew A PerrasSimon LoewKerry Leith We aim to advance the frontier of progressive rock failure combining laboratory data derived from new custom built creep testing machines (capable of regulating temperature, humidity, and mechanical load over at least 100 days) with measurements from existing field equipment. Initial testing will be focused on unique natural and man-made […]

Research project: GlacierRocks – Glacier-Headwall Interaction and its Influence on Rockfall Activity
Ingo HartmeyerMarkus KeuschnigJan-Christoph Otto Kay HelfrichtKerry Leith Michael Krautblatter Institutions: GEORESEARCH Forschungsgesellschaft mbH, University of Salzburg, Technische Universität München, Austrian Academy of Sciences, ETH Zurich Goal: The proposed project GlacierRocks will establish the worldwide first research site for long-term monitoring of stability-relevant processes inside a randkluft system. Based on the acquired monitoring data GlacierRocks is pursuing […]

Candidate: Martin Kradolfer Supervisors: Florian Amann, Kerry Leith Institution: ETH Zurich Activity: Beginning Fall 2017 Project Framework: Ice filled tension cracks are commonly observed in association with active or catastrophic rock slope failures located in potential permafrost regions of the Alps. Displacement or dislocation along cracks in many of these rock slopes has been observed to primarily occur […]

Candidate: Patricia Hug Supervisors: Kerry Leith, Andrea Manconi Institution: ETH Zurich Activity: Beginning Spring 2018 Gaining a better understanding of processes that contribute to the formation of large rock slope failures can provide important insight into their mechanics and future development throughout the Alps. Such instabilities are commonly assumed to be initiated as a result of erosion, seismic activity, or […]

Gaining a better understanding of factors that contribute to the location of rainfall-induced landslides affecting alpine transport networks is an important first stem in protecting against such events, and maintaining access to critical regions during intense weather events. Three days of late monsoon rainfall in the Bhutan Himalaya this year generated an unprecedented degree of […]

Employing a new portable acoustic emission detection system, this project will investigate the correspondence between key environmental variables (air and rock temperature, humidity, wind, and […]

The global increase in atmospheric temperature may be accelerating the physical breakdown of landscape and infrastructure. Rock expands when heated, and combined with other stresses in the landscape associated with topography and regional tectonic history, can potentially trigger the formation of large rockfalls. Recently, large bedrock outcrops in California and Finland hosted dramatic fracturing events […]

Geological materials change their strength properties through time, which has significant implications for the stability of natural and artificial slopes, surface or subsurface excavations, and deep boreholes used for energy production. The Engineering Geology Group at ETH Zurich will organize a conference to address these critical topics in a subsidized event overlooking Lake Maggiore in […]

Candidate: Andrina Vlasek Supervisors: Kerry Leith, Andrea Manconi Institution: ETH zurich Activity: Completed summer 2016 Natural hazards such as landslides happen frequently in Switzerland, more than 6% of Switzerland’s area is prone to slope instability. Not all landscapes are equally prone to landslide instabilities, but depend on various factors, such as geologic (e.g. lithology), topographic (e.g. slope steepness) […]
